Barrier Paper In picture framing, a thin, acid-free film laid over or behind an artwork to protect it from negative interaction with non-archival materials. The term can also describe the "dust cover" or "backing paper" applied around the back of a picture frame once the contents are in place, to keep dust and environmental substances from damaging the art.
